Like the MAX6025, the TSM6025 consumes only 27μA of supply current at no-load, exhibits an initial output voltage accuracy of less than 0.2%, and a low output voltage temperature coefficient of 15ppm/°C. In addition, the TSM6025’s output stage is stable for all capacitive loads to 2200pF and is capable of sinking and sourcing load currents up to 500μA. Since the TSM6025 is a series-mode voltage reference, its supply current is not affected by changes in the applied supply voltage unlike twoterminal shunt-mode references that require an external resistor. The TSM6025’s small form factor and low supply current operation combine to ma...
